The area to be secured is a collection of abandoned historic mill buildings in Greenfield Valley Heritage Park near Flintshire in Wales. The structures have become a haven for vandals who threaten to destroy the site. And bees would theoretically be cheaper than a highfalutin high-tech security system.
